The band that toured with Mastodon? Yeah Sumerian bands would easily open for TDEP.

Agreed but they are a much different band than the rest of the labels current roster. It will be interesting to see how they handle promotion and touring but I would not be surprised to see them go out with a band like Stray From the Path or Structures, maybe even Periphery as support.

Periphery supported Dillinger in Australia before. I think it's good for both sides. Sumerian know how to promote and get tours for their bands, and Dillinger should help the label be more accepted by the metal community.
